HORSESHOE AND BEPLAOEABLE BAD THEREFOR.

Application filed January This invention relates, to horseshoes, and more particularly to an improved horseshoe and .a replaceable pad therefor.

It has been the custom heretofore to use a resilient cushion or pad for horseshoes which is interposed and rigidly fixed between the metallic shoe and the horses hoof. WVhen the pad wears down and has to be replaced, it is necessary to remove the steel shoe even though the latter is still good. It is quite apparent that this procedure is a very 1neflicient one and has many disadvantages.

On the other hand when a pad is used with a shoe having replaceable toe calks, it is necessary to use a special toe calk. This special calk is only about one-half of the height of the standard calk; and hence has to be replaced very frequently. 7

It is an object of the present invention to provide an improved horseshoe and a resilient replaceable pad therefor which elim nates the disadvantages noted heretofore, and in addition possesses many advantages to be pointed out hereinafter.

Other objects of the invention are to provide a resilient pad which is quickly replaceable on the shoe; which can be used with standard toe calks; which gives adequate support and ventilation to the horses hoof; and which is simple and economical to manufacture.

This invention will be better understood from the following description taken in conjunction with the accompanying drawings, in which Fig. 1 is a bottom plan view of an embodiment of my invention;

Fig. 2 is a side elevation of Fig. 1;

Fig. 3 is a rear elevation of Fig. 1;

Fig. 4 shows a sectional View on the line 4-4L of Fig. 3; and

Fig. 5 shows a sectional view on the line 55 of Fig. 2.

Similar characters of reference designate similar parts throughout the accompanying drawings. The numeral 1 portion of my improved horseshoe which may have any usual or preferred form. The body portion is provided with a plurality of ordinary nail holes 2 and a front toe 3. This toe may be of any type, but the present invention is especially useful with the replaceable calk type.

The rear ends 4 of said body portion are bent down to form a pair of shoulders 5.

designates a U shaped body 18, 1926. Serial No. 82,003.

From the inner side 6 of each shoulder an offset projection or coupling bar 7 extends rearwardly of and in a lower plane than the body of the said shoe, thesaid projections being secured to the shoulders in any wellknown manner or being made integral with said shoulders. Each of said bars passes through a hole 8 positioned in a resilient replaceable or removable heel pad 9 and extending from the front to the rear thereof. These holes are of such-a size that they will accommodate the projection bars even after they are adjusted by thefarrier in any particular case. This pad may be made of suitable resilient or shock-absorbing material such as rubber-composition, leather, etc., and comprises a main body portion 16 which has a frog-surrounding or hoof-bearing portion 18 at the upper side thereof, and a tread portion 17 at the lower side thereof. The upper or frog-surrounding portion of the pad is hollowed out as shown at 30 so that the'frog of the horses hoof fits in the depression thus made. In order to facilitate the removal or application of the pad from or to said offset projections on the shoe, a tool-engaging means, such as a tongue 19, may be incorporated with said pad. If desired a liner 40, preferably of metal, may be inserted in each of the holes of said pad to reinforce the inner surfaces thereof.

The replaceable pad may be held in position with any suitable fastening means, such as .a detachable bearing plate 10 fastened adjacent the end of each of said coupling bars. The detachable bearing plate is prefera-bly made of metal, and has a substantially central opening 11 therein adapted to fit on the endof each offset projection. This plate is secured in place by a cotter-pin 12, which is passed through a hole 13 in and near the end of said bar. Of course, the area of the plate is large enough. to afiord adequate pressure and bearing surface against the rear of the pad. If preferred, these two plates may be united into a single plate with two holes to fit on the coupling bars.

The method of using this shoe is obvious to those skilled in the art. The steel shoe is nailed to the horses hoof after it has been fitted and adjusted, the projection bars extending rearwardly in substantially a perpendicular direction to the rear of the horses hoof. The replaceable pad is now inserted on the bars which pass through holes 8. The

fastening clips 10 are slipped over the free ends of the bars, and are forced against the rear of the pad by the cottor-pins. When the pad is worn down and has to be replaced, the detachable plates or clip are removed from the coupling bars or projections. The pad may then be withdrawn by grasping the tongue with a pair of pliers. 'Of course, this operation is efiected without the necessity of removing the shoe from the horses hoof. A new pad is quickly slipped on the bars into proper position and locked or se cured in that position by the bearing plates and cotter-pins as'noted heretofore. In this manner the pad is held securely in position and is prevented from slipping back and forth.

It will be observed that the present 1nvention provides a shoe which may be used for longperiods without the necessity of removing the same every time a new pad is put on. This is especially true if my present invention is used in conjunction with a replaceable toe calk, such as disclosed 1n my Patent #1,4.72,025 issued-October 23, 1923, or in fact with any of the well-known replaceable toe calks. The main body portion may be used as long as desired without removal, because when either the calks or the pads are worn they may be easily and quickly replaced.

It will be further noted that my improved shoe has the replaceable pad positioned thereon so that it bears properly around the frog of the horses hoof, and thus relieves the horse from undue strain of jars and con cussions. Moreover, the entire inner portlon of the horses hoof is exposed so that perfect ventilation is insured, and that the natural processes occurring there are not interfered with.

It will also be noted that my improved horseshoe may bemade by a simple forging operation which insures a low initial cost. This shoemay be made in any desired form or type, including light and'draft types. Furthermore, my invention provides an economical resilient pad capable of being used with full-size standard replaceable toe calks, so that a user realizes a longer life with his calks before having to replace them with new ones.

While I have illustrated and described a preferred form of construction for carrying my invention into efiect, it is understood that variations in the embodiment may be made without departing from the scope and spirit of the invention.

I claim:

1. A horseshoe having a pad removable from the rear thereof, said pad being secured at the rear face thereof.

2. In combination, a horseshoe having a U-shaped body portion with offset pro ections extending to the rear thereof in a different plane from said body portion, a pad having holes therein to fit said projections, and removable fastening means operatively associated with said projections to hold said pad securely in position.

4t. lncomblnation, a horseshoe havlng a U-shaped body portion, projections secured to the rear ends thereof, a resilient pad having holes therein to fit said projections, and a detachable plate for each of said projections to hold said pad snugly in position.

5. A resilient replaceable heel pad havinginternal holes therein for horseshoes, comprising a main bodyportion having the said holes extend internally from the front to the rear of said pad, a tread portion at the bottom thereof, and a hoof-bearing portion at the upper side thereof.

6. A resilient replaceable heel pad having internal holes therein for horseshoes, comprising a main body portion having the said holes extend. internally from the front to the rear of said pad, a tread portion at the bottom thereof, a hoof-bearing portion at the upper side thereof, and inserts fitting said holes.

7. A resilient replaceable heel pad having internal holes therein for horseshoes, comprising a main body portion having the said holes extend internally from the front to the rear of said pad, a tread portion at the bottom thereof, a hoof-bearing portion at the top thereof, and metallic inserts fitting in said holes. Y

8. A resilient replaceable heel pad-having internal holes therein for horseshoes, comprising a main body portion having the said holes extend internally from the front to the rear of said pad, tool-engaging means incorporated therewith, a tread portion at the bottom thereof, and a hoof-bearing portion at the top thereof. f

9. In combination, a horseshoe having a U-shaped body portion, projections located at the rear ends thereof and formed integral with the said body portion, a resilient pad having holes therein to fit said projections, and removable fastening means operatively associated with said projections to hold said pad 'securely in position. i

In witness whereof I have hereunto set my hand.
